  • Patent number: 6237875
    Abstract: An airbag configuration for braking the landing impact of flying payloads has a central airbag (17) and at least one torus ring (11, 12, 13) surrounding the central airbag. A payload (L) is attachable on the central airbag (17). A stabilizing device (19) is provided which extends from the lowermost portion of the at least one torus ring (11, 12, 13) to the central airbag (17). The central airbag provides primarily vertical braking of the landing impact while the torus ring provides primarily horizontal braking of the landing impact.

  • Patent number: 5826826
    Abstract: A landing process and arrangement for payloads from aerospace missions with a steerable gliding body deployable at high altitudes for accurately returning the payload to the earth surface wherein delicate and stressable elements of the payload are to be recovered. The gliding body is filled with a light gas during its deployment, and the aerostatic lift must be lower than the weight of the landing unit. The payload is divided into a body with delicate elements and a body with stressable elements, wherein the body with the stressable elements is suspended on a pulling element at a spaced location under the other body. After the lower body has come into contact with the ground, the upper body is maintained suspended aerostatically.
